How many systems do you have?

Garage (old vintage stuff)

Studio/Office (very budget but enough for Qobuz and YouTube)

Den (main rig)

living room (music/tv/movies)

I have a 7.2 in my master bedroom (there was a hissy but she’s better now). I swap I swap out the front mains every few months.  I have my reference 5.2 in my basement theater. I also have a separate two channel system in the same space. I have fourteen pair of speakers in storage and four additional amps and preamps also in storage.  
 

I have a problem. 

Five in the music room

Sonic Frontiers and 6n7 monos with Altec A-5

Nak stack with Zaph Audio 12.3

Cary SLI-80 with epsilon speakers

Musical Fidelity M6PRE and M6PRX with Summit X speakers

Musical Fidelity KW system with Magnepan 3.7i speakers

goal is to pair down to two

oh and 1 in the living room and garage

I am a sick man !

Three. All aimed at acoustic music but with different ways to get there. It’s brand name, high-power components plus vinyl in the listening room, then low-power, class-A Pass DIY amplification with high-sensitivity DIY speakers in the family room, and diy First Watt/Pass “tube” preamp in the living room.

Three.  Main in living room.  Secondary in dining room/den (sounds as good but slightly different than main.)  Tertiary in bedroom.  All handle CD/SACD, first two phono as well.  All have tuners.  First system has RtR Dolbyized tape; bedroom has Nakamich cassette.  No streaming (at least not yet; perhaps not forever.)
